Due to the dry / wet cycle of the electrolyte membrane accompanying start / stop of the electrolyte membrane for fuel cell, orientation of the polymer chain in the electrolyte membrane deteriorates the electrolyte membrane. This degradation is analyzed by polarized light. We report the in-plane distribution of macromolecular chain orientation over the birefringence and report the in-plane stress distribution.
